The childhood type—juvenile nephronophthisis—is an autosomal recessive disorder caused by mutations in any of 20 NPHP genes; the type appearing in adulthood—medullary cystic disease—is autosomal dominant. Both types are manifested by multiple small renal cysts at the corticomedullary junction and medulla. The cortex becomes fibrotic, and as the disease progresses, interstitial inflammation and glomerular sclerosis develop.
